Hot insulation with zinc rich epoxy alone

Hot insulation with zinc rich epoxy alone

Hot insulation with zinc rich epoxy alone

Can Zinc rich epoxy alone be used under hot insulation temperature range 60-80degree?

RE: Hot insulation with zinc rich epoxy alone

Epoxies will withstand continuous exposure to 60-80 C, and the addition of Zn won't change that. Yes, you can insulate lines coated with Zn rich epoxy if your service temperature will only be 60-80 C.

RE: Hot insulation with zinc rich epoxy alone

Thanks Moltenmetal,
But isn't zinc prone to formation of rusting under insulation when moisture ingress.
I would appreciate your response.


RE: Hot insulation with zinc rich epoxy alone

What if temperature is up to 120 degree continous.

RE: Hot insulation with zinc rich epoxy alone

120 C is marginal for an ordinary epoxy. It will be more protective than no coating, but not as protective as if it were operating cooler.

RE: Hot insulation with zinc rich epoxy alone

Consult NACE SP0198 for guidance.
